IMPROVEMENT lN HYDRAULIC NOZZLES.

Specification forming part of Letters Patent No. 177,419, dated May 16, 1876; application filed I January 17, 1876. I

moving the discharge-nozzles of hydraulic machines from side to side, or so as to point in any desired direction and this I effect by means of the deflecting power of the streams from the nozzle itself, through the intervention of suitable plates or devices, which are readily operated, so that the stream will operate them from any desired direction;

Referring to the accompanying drawing for a more complete explanation of my invention, Figure l is a perspective view.

A is the discharge pipe or nozzle of a hydraulic machine, such as are used for washing down banks in What are known as gravel gold-diggings.

These nozzles are usually of large diameter, and water is brought to them under great pressure, so that it is very difficult to move the universal joint with which they are construmTn'aIIydevices comprising powerful levers have been used for the purpose. I have found, however, that by suitably-manipulated tubes, plates, or rifles, the force of the stream issuing from the nozzles may be made to turn the pipe in any direction without the use of any other device.

In the present case I have shown a short section of the tube B, which may be somewhat' larger than the nozzle, (that isif the nozzle be six inches in diameter, the interior diameter of the tube may be seven inches,) so

that when mounted upon the pipe, just beyond or ahoutthe end of the nozzle, the stream of water will pass through it without touching, but, it the tube be turned to either side, the force of the water acting against the side will cause the whole nozzle to move in that direction.

In order to mount the tube,"so as to move it readily in any direction, I have secured it to one arm of a lever, C, while the other arm extends back along the line of the pipe. The fulcrum of the lever is supported upon a swivel -joint, D, which is capable of being turned in any direction. This joint is supported from a ring surrounding the nozzle, or gimbals may be fitted to support the deflectinglnozzle.

It will readily be seen that distinct deflecting plates might be substituted for the nozzle ortube; or in some cases a rifle or plate might be mounted like a butterfly-valve upon an arm passing through the side of the nozzle near its end,so as to stand in the stream, and

by turnin g this plate from side to side the desired efiect might be produced. A rest, E, serves to support the lever O and retain the deflector in a straight line when not needed.

By this means I do away with the powerful mechanism needed to operate these large nozzles, and reduce the labor so that a child could manage the largest machine. 7

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-- 'lhe deflector B, with its universal joint D, or equivalent device,'and operating lever O, in combination with the nozzle of a hydraulic machine, substantially as and for the purpose herein described.
